Ground water year book of Kerala (2019-2020)
To build a realistic ground water management strategy, assessment of ground water availability and its quality is a pre-requisite. With this in view, Central Ground Water Board has established a network of Ground Water Monitoring Wells (GWMW) tapping different aquifers in the State. Presently, there are 1602 GWMW in Kerala state, out of which 1381 are dug wells tapping phreatic aquifers and 221 are bore wells/tube wells tapping deeper semi-confined/confined aquifers, which are monitored four times a year. The document Ground Water Yearbook Kerala (2019-20) is a compilation of water level and water quality data collected from these wells during 2019-20.
